Guildford PV installation

From the initial site visit, through the installation and commissioning of the PV panels, the battery and car charger, Sussex Solar have provided exemplary service. All those involved in the process were fully professional and the installation was completed on time, within budget and all paperwork provided efficiently. We were kept up-to-date and fully informed throughout and were impressed to receive a follow-up site visit. We would definitely recommend Dominic and all the team at Sussex Solar.

High quality bespoke install - SOLAR & Battery I wanted a PW3 & solar installation - Dom and the team at SS do quality work with attention to detail. Cables and units installed exactly where I wanted for maximum aesthetics. From the back office staff to installers all were a delight. Very neat and tidy installation and works as expected first time. Thoroughly professional team who know what they are doing and care about their standard of work which is exemplary.

Great job on Heat Pump, Solar Panels and Battery installation

Sussex Solar supplied an Air Source Heat Pump, PV Solar Panels, Battery and Grid Gateway to our home and did an excellent job right from the initial enquiry and informative survey, through installation and final commissioning. The installation team were brilliant in ensuring we were without hot water and heating for only a minimal period and the installation itself is so neat and tidy. We're very pleased with the result and would thoroughly recommend. (We used Sussex Solar for thermal and PV panels on our previous home and were very pleased with those projects too - and the great aftercare service received over the past 15 or so years)

Another good job for us by Sussex Solar

Sussex Solar have been back to do another job for us! I think we first used them about 16 years ago to install a solar thermal system. Next came a solar PV system. Then about 3 years ago a 12kw Vaillant air source heat pump to replace our gas boiler. Now, more PV panels and a Tesla Powerwall. In each case, they gave good advice, designed a robust system, and installed it to a high standard on time and on budget. The few items of servicing that have been necessary have also been handled well. I highly recommend them for the range of products and services they offer.

Decided to invest in Roof Solar PV panels, Tesla Powerwall 3 and Zappi charger. From first contact with Sussex Solar in December, through reviewing our options, agreeing a project and the completion of the installation at the end of January, the whole process was straightforward and very professional. What I valued most was the care and quality of work carried out by every member of their team. It was a pleasure to have them work at our home. In addition, the communication with their office planning team was first class. Our Solar Thermal system was also serviced again, as part of the overall project. System working to plan and when the sun shines, wow!!

Tesla Powerwall3 Battery Installation

Delighted with Powerwall3 product for Load Shifting, also excellent installation process, efficiency, speed of quote and answers to questions. Everything I wished for was achieved. Electrical work neat, tidy, and proficient. The standout feature is the professional but positive likeable attitudes of all staff and business owners. I will not hesitate to select Sussex Solar in future, if or when I consider maybe solar, heat pump, or another battery. A pleasure when first time using a new supplier that they not only meet but exceed expectations.

ASHP Heating Project
Customer Service
Quality
Value
I came across Sussex Solar while researching ASHP heating solutions through Heat Geek, and I was pleased to find that they are a recommended installer by Vaillant. Andy from Sussex Solar promptly visited to assess my project, taking detailed measurements and photos. Within a week or so, I received a comprehensive quote from them. While I had other companies provide quotes, Sussex Solar stood out for their clear understanding of my project requirements and timelines. What has impressed me was their willingness to collaborate and adapt to my needs. Throughout the project, communication with Sussex Solar has been good, shout out to Charlotte here, ensuring that every step, including the BUS grant application was transparent and well-coordinated. The only issue I had was with the base of the ASHP where it was not clear from the instructions given how far it needed to be from any wall. Other than that, I wholeheartedly recommend Sussex Solar to anyone considering an ASHP related project. Special mention to Lewis, Finley, Wes and George for a faultless installation.

We engaged Sussex Solar to install a ground-mounted array, after enquiries with a few other bigger firms had come to nothing. They were very helpful and responsive during the quotation, planning and installation process, and we wouldn't hesitate to use them again.
